WILHELM MOLI'JER, OF LEWISTOWN, PENNSYLVANIA, ASSIGNOR TO EASY PAN GREASING MACHINE 00., OF PHILADELPHIA, PENNSYLVANIA.

PAN-GREASING maonrnn Application filed June 14, 1924. Serial No. 720,077.

To all whom it may concern:

Be it known that I, WILHELM MOLLER, a citizen of the United States, residing at Lewistown, in the county of Mifliin and State of Pennsylvania, have invented certain new and useful Improvements in Pan- Greasing Machines, of which the following is a specification.

My invention relates to machines for greasing pans for use in baking.

The usual method of greasing pans by machine is by rotating a series of vertically projecting brushes, manually greasing a portion of the first pan, inverting the an and sliding it over the brushes. The rst pan primes or feeds the grease to the brushes, the other pans are greased by sliding them over the brushes. The first pan is liberally, if not excessively, greased and each succeeding pan gets less grease until the grease on the brushes is practically exhausted when another pan must be greased manually. To lengthen the life of the bristles, the brushes are rotated alternately in reverse direction, and the abrupt stopping and starting of the reciprocating parts by which the alternating motion is eflected soon wears and loosens the parts and the machine becomes noisy.

The objects of my invention are to provide a machine which may be manipulated to feed any desired amount of grease; in which the brushes are rotated alternately in reverse directions without abrupt stopping and starting of the reciprocating parts, and in which the positions of the brushes may be adjusted for use with pans of different size.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a vertical section through a machine constructed in accordance with my invention looking in one direction,

, Figure 2 a like section looki g in the other direction,

Figure 3 an enlarged section on line 33 of Figure 2,

Figure 4 a plan view, partly broken away, of the machine shown in Figure 1,

Figure 5 a section on line 55 of Figure 1, and

Figure 6 a section on line ure 1;

Referring to the drawings, lindicates a 66 of Figframe of suitable construction having a compartment 2. A pair of spaced supporting guides 3, preferably of angle iron, are

mounted on angle brackets 4 secured to the end walls 5 of compartment 2. A series of step bearings 6 are'slidably mounted at one side of guides 3 by passing a pair ofbolts through the bearings and between the as guides, to the other side and securing a spring-pressed clamping plate 7 on the bolts. The spring-pressed clamping plate engages the other side of guides 3 and holds the bearing 6 to the guides. The bearings 6 may be adjusted toward or away from each other by a screw 8 havinga threaded connection with the bearing at 9, rotatabl mounted in end wall 5 at '10, and held against lengthwise movement by a collar 11 disposed between end wall 5 and angle bracket 4. An angular end 12 is formed on the end of each screw to fit a crank handle for turning the screw to adjust the bearings.

A spindle 13 has one end rotatably mountso ed in each bearing, and a brush 14 detachably connected to the other end. A stem 15, secured to the lower end of bearing 6 by a nipple 16, passes upward through spindle 13 and brush 14 to a point adjacent the top of the body ofthe brush which is counter-sunk as shown at 17. Stem 15 has its upper end closed and its cylindrical wall perforated near the top so that grease passing upward through fiected radially against the conical surface 17 and onto the bristles of the brush. The grease is fed to the stem through a flexible tube 18 connected with nipple 16 and a pump 19 mounted in a tank 20. Pump 1915 7 preferably consists of a cylinder 21 having the stem will be demi an inlet check valve 22 and an outlet check valve 23 near its lower end and a plunger 24 sliding in the cylinder for sucking the rease from the tank into the cylinder and orcing it out of valve 23 through tube 18 and stem 15 to the bristles of the brush. A pump is provided for each stem 15. These umps are preferably arranged in a manifo d and se cured to the tank as shown at 25 and the plungers are connected to a common bar 26 which has a pin and slot connection with an operating lever 27 pivoted at 28 to tank 20., The free end of the operating lever extends through a slot in the end wall 5.

Each brush-carrying spindle receives its alternate rotation in forward and reverse direction, through a gear 29 fixed to the spindle and a meshing rack 30 slidably mounted on the upper supporting guide 3. A slotted cross head 31 carried by rack 30 is operatively connected with a crank pin 32 carried by a. crank 33 on a shaft leading to a reduction gear 34 which is connected with a motor 35. A rotary movement of crank 33 is transformed to a harmonic reciprocating motion by crank pin 32 and cross head 31 and transmitted to rack 30. The cross head is preferably constructed of a pair of spaced bars 36 secured to the rack and having spacers 37 secured therebetween. Crank in 32 preferably carries an anti-friction roiler 38 which travels between the bars 36. Rack 30 is ided inits sliding movement by its meshing gears 29 at one side,

ide rollers 39 mounted on supporting guide 3 on the other side, wearing plates 40 on its lower side, and wearing plates 41 on its upper side. Wearing plates 40 are secured to the upper supporting guide 3 and wearing plates 41 are secured to housings 42 fixed\to end walls 5. These bone in revent ob'ects from getting between th eiids of radk 30 and the end walls 5. Wearing plates 40 and 41 are preferably made of hard fiber which will retain a lubricant and prevent objectionable noises.

A drip pan 43 covers the top of the frame and serves to catch any grease which may dro from the brushes. Pan 43 has a longitudinal slot 44;. through which spindles 13 project. Slot 44 is covered between the the spindles by U-shaped telescoping sections 45 having a spindle 13 passin through each section. The sections ovelfiap each other so that an adjustment of the brushes will slide the sections relatively to each other. Any ase dripping from the brushes direct y over the slot will be deflected from the slot by these telescoping sections.

To use the machine, the motor is started and rotates the brushes alternately in reverse directions. Lever is manipulatedtoforcegreasefromtankwthrough brushes and operatively connected tube 18 and stem 15 to brushes 14. A pan is inverted and slid over the revolving brushes until it is properly greased. To grease different sized pans, the brushes are adjusted toward or away from each other by turning the screws 8. During the adjusting movement of the brushes, telescopmg sections 45 will slide on each other without interfering with the adjustment.

It will be seen that, with the machine above described, the brushes will berotated alternately in forward and reverse direction without abruptly stopping and starting the reciprocating parts connected therewith; the machine will run smoothly and quietly; none of the grease falling from the brushes will drop on moving parts the brushes may be adjusted to grease difierent sized pans, and any dwired amount of grease may be fed to the brushes without being touched by hand.

While I have described my invention as taking a particular form, it will be understood thatthe various parts may be changed without departing from the s irit thereof, and hence I do not limit myseff to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.
